Plasma nitriding can thus be performed in a broad temperature range, from 260 °C to more than 600 °C. [4] For instance, at moderate temperatures (like 420 °C), stainless steels can be nitrided without the formation of chromium nitride precipitates and hence maintaining their corrosion resistance properties. [5]
The steels can be nitrided to increase case hardness and polished to a fine surface finish. Non-stainless varieties of maraging steel are moderately corrosion-resistant and resist stress corrosion and hydrogen embrittlement. Corrosion-resistance can be increased by cadmium plating or phosphating.
It is 0.05 mm (0.0020 in) thick and produces a 64 Rockwell C hardness rating via a 500 °C (932 °F) nitride bath. [33] The final matte, non-glare finish meets or exceeds stainless steel specifications, is 85% more corrosion resistant than a hard chrome finish, and is 99.9% salt-water corrosion resistant. [34]
The process starts with a standard salt bath nitrocarburizing cycle, which produces a layer of ε iron nitride. [4] Next, the workpiece is mechanically polished; typical polishing processes include vibratory finishing, lapping, and centerless grinding. Finally, the workpiece is re-immersed into the salt quench bath for 20 to 30 minutes, rinsed ...
Nitronic alloys were developed by Armco Steel. The first of these alloys, Nitronic 40, was introduced in 1961. [1] Since 2022, the trademark has been owned by Cleveland-Cliffs Steel Corp., successor to AK Steel. [2] Electralloy is the licensed producer in North America for a wide range of Nitronic products.

In 200 series stainless steels the structure is obtained by adding manganese and nitrogen, with a small amount of nickel content, making 200 series a cost-effective nickel-chromium austenitic type stainless steel. 300 series stainless steels are the larger subgroup. The most common austenitic stainless steel and most common of all stainless ...
